摘要： A process for forming a cross-linked thermoplastic elastomer is disclosed herein. The cross-linked thermoplastic elastomer is a thermoplastic cross-linked copolyester and is preferably formed by heating a first mixture containing a thermoplastic elastomeric base material, a monomeric diisocyanate comprising between 1 to 10% of the total weight of the first mixture, and a second mixture of a first diamine and a second diamine comprising between 1 to 10% of the total weight of a total reaction product. The heated first mixture, which is flowable, is injected into at least one injection molding device, with the second mixture injected at predetermined intervals to create a homogeneous reaction product. The reaction product may be injected into a mold to produce articles.

摘要： A railway car truck is provided that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The pedestal opening is formed by a roof section that includes a pad receiving opening. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of a bearing assembly. An adapter pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. The adapter pad includes a base section and a raised top section that is fit within the pad receiving opening in the pedestal roof section.

摘要： A polymer spring has a hollow tubular polymer body, wherein the first end portion of the body, the second end portion of the body, and the mid-portion of the body together substantially maintain an annular cylindrical column structure throughout the length of the body from the first end portion of the body to the second end portion of the body, such that the mid-portion of the body has a substantial portion that is in direct alignment with the first end portion of the body and the second end portion of the body when the spring is compressed to eliminate or reduce the chances of the spring failing caused by the spring folding or buckling and to reduce material fatigue in the polymer spring associated with folding or buckling.

摘要： A resilient pad having a base with two side arms and two side lips for resiliently holding the base on a pedestal wear plate, the pad being configured with dome shaped portions disposed substantially perpendicular to the direction of the pad and being spaced apart from each other, where the pad, when installed with a pedestal wear plate serves to improve the force load handling and preferably re-distributes the load bearing surface from the edges and center of the adapter to the flat load bearing surface of the adapter, thus eliminating load on areas that have no support. Because the spring arms do not depend on bending of the base for their resiliency, the pad of the invention provides improved service stress capabilities and allows for longer life of the wear plate.

摘要： A wear plate for use with a railway truck, the wear plate being configured for installation on a downwardly facing surface of a pedestal opening of a side frame of a railway truck. The wear plate includes a base and a pair of side walls extending upwardly from opposite sides of the base with inwardly disposed locking features designed to engage the pedestal when the wear plate is installed, the locking features in a preferred embodiment being configured as resilient projections that engage, clamp or drag lock onto opposite sides of the pedestal with the base of the wear plate protecting the downwardly facing pedestal surface. The wear plate may be constructed from malleable or ductile metals or plastics.
